The Type 80 Electric Punched Card Sorting Machine was the first horizontal card sorter, introduced by IBM in 1925 to operate at almost twice the speeds of the older Type 70 vertical sorter.

80 [2]

This machine used a direct magnetically operated control for the chute blades which replaced a much more complex mechanical device in the older machine. The Type 80 grouped all cards of similar classification (such as "sales by products") and at the same time arranged such classifications in numerical sequence. With 10,200 units on rental at the close of 1943, the Type 80 had the largest inventory for any machine at that time.
